J'U'IJIUS DE LONG, 0E NEW YORK, N. Y.,

AND JOHN BAPTISTE DHOMERGUE, OF

PITTSBURGH, PENNSYLVANIA.

To all 'whom t 'may concern Be it known that we, JULiUs DE Lone, a citizen of the United States, residing in the borough of Brooklyn, in the city of New York, in the county of Kings and State of New York.v and Jol-IN BAPTISTE DHoMER- con, a citizen of the United States, residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in lnsulating Material for Buildings, Refrigerating-Cars, Refrigerators, and other Purposes, of which improvements the following is a full and complete specification.

Our invention relates to insulating inaterial -for buildings, refrigerating cars aud analogous purposes, such as is generally used in the walls of buildings, refrigerating cars and other refrigerating apparatus, and the object of our invention is to provide a material which shall be particularly suitable for refrigerating cars and refrigerators and other analogous purposes, and which shall be simple, durable, eliicient and inexpensive, and atthe same time antiseptic in its qualities.

These and other objects will more readily appear to those skilled in the art as the description of the case proceeds, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated and claimed.

ln theV accompanying drawing, the figure is a cross-sectional view of our invention.

Referring specifically to the drawing, the numeral 1 designates a covering, which is of tough waterproof paper or other suitable material. 2, a filler of insulating material, and 3, the other protective sheet, which is likewise of tough waterproof pa- Specification of Letters Patent.

per or other suitable material. The filler 2, consists of cleanly washed bog-fiber, which, inl structure and appearance, closely resembles cattle hair. If this liber is comparatively long and tough, it alone may be used as the filler between the retaining sheets l and 3. If the filler, however, is short and more easily crumbled, I mix with it the proper proportion of cattle hair, which, being unbreakable, readily retains the shorter fiber in place between the sheets. Clean bog-liber like cattle hair cannot be closely packed, and consequently, there are many intervening air spaces between the fibers, and as bog-liber is a poor conductor of heat, it forms an excellent insulating material, and at the same time it possesses marked antiseptic qualities Which render it exceedingly desirable for insulating refrigerating ears and refrigerators, and it may he obtained in very considerable quantities at far below the cost of cattle hair.

Having thus described the nature and object of our invention, what we claim as new. and desire to secure by Letters Patent 1s:

An insulating material comprising spaced holding sheets, and an antiseptic dry filling consisting of unfelted loosely intermingled Y bog fiber and cattle hair.

Signed this twentieth day of May, 1914.
